Riot police in Hong Kong today arrested scores of students who stormed the government headquarters compound during a night of scuffles to protest against China's refusal to allow genuine democratic reforms in the semi-autonomous city.

More than 100 other protesters, however, showed no sign of leaving the area surrounding the square where the government complex is located, and chanted at police to stop arresting their colleagues.

The dispersal followed a night of scuffles between police and about 150 protesters who forced their way into the government compound, some scaling a tall fence. Police on Friday night responded with pepper spray to push them back, but about 50 had remained inside the gated premises.

At least 29 people have been injured since Friday night, police said.

Hong Kong Secretary for Security Lai Tung-kwok told reporters that police acted appropriately and gave students sufficient warning before starting the process of clearing the square.

The scuffles came out of the end of a week-long strike by students demanding China's Communist leaders organise democratic elections in 2017.

Tensions over Hong Kong's political future have risen significantly since control of the former British colony passed to China in 1997.

China's leaders have promised universal suffrage for the city, but last month ruled out letting the public nominate candidates, instead insisting they be screened by a committee of Beijing loyalists.

Hong Kong's young people have become vocal supporters of full democracy in recent years, fueled by anger over widening inequality.

Thousands of university and college students who had spent the week boycotting classes were joined on Friday by a smaller group of high school students.

Organisers said those arrested at government headquarters included Joshua Wong, a 17-year-old leader of the activist group Scholarism, who was dragged away by four officers. Wong, a recent high school graduate, gained prominence two years ago after he organized protests that forced the Hong Kong government to back off plans to introduce a Chinese national education curriculum that some feared was a form of brainwashing.

"Our movement is peaceful and does not use aggression," said University of Hong Kong students' union president Yvonne Leung. "Students who decided to storm inside (the government complex) knew about their legal responsibility."

The student protest was organized independently of Occupy Central, an alliance of pro-democracy activists planning to blockade Hong Kong's financial district to call for genuine democratic reforms.

On Saturday, several Occupy Central members joined students protesting outside the square.

Benny Tai, a key leader of the movement, told reporters that the group would "stay with the students until the end and risk getting arrested ourselves." Tai criticized the amount of force police used on students.

Occupy Central has hinted that its blockade will begin Wednesday, China's National Day holiday.
